嵐的QQ WEEK02

 1.開啟GLUT和OPENGL

2.整理GLUT的程式碼至下方

程式碼:

#include <GL/glut.h>

static void display(void)

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}

int main(int argc, char *argv[])

{

    glutInit(&argc, argv);

    glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE | GLUT_DEPTH);

    glutCreateWindow("08160864");

    glutDisplayFunc(display);

    glutMainLoop();

}

3.茶壺形成

4.參數觀念

5.加入一行 glColor3f(1,0,0);改變顏色

茶壺紅色

6.先做三角形再做茶壺

glBegin(GL_TRIANGLES);

        glColor3f(1.0f,0.0f,0.0f); glVertex2f(0.0f, 1.0f);

        glColor3f(0.0f,1.0f,0.0f); glVertex2f(0.87f, -0.5f);

        glColor3f(0.0f,0.0f,1.0f); glVertex2f(-0.87f, -0.5f);

    glEnd();

    glColor3f(0.5,1,0.2);

7.  glBegin(GL_LINE_LOOP);

 

8.void display()

{

    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

    glBegin(GL_POLYGON);

        glColor3f(1.0f,0.0f,1.0f);

        for(float angle=0;angle<3.14159265358979*2;angle+=0.01){

            glVertex2f( cos(angle),sin(angle) );

        }

    glEnd();

    glColor3f(0.5,1,0.2);

    glutSolidTeapot(0.3);

    glutSwapBuffers();

}
